Enhanced Hygienic Design Wall Mounted Enclosures
Now in the Market

In response to customer feedback, nVent HOFFMAN has added new features to the Hygienic Design HDW range of wall mounted enclosures specially designed to protect electrical equipment in harsh sanitary washdown and clean-in-place (CIP) procedures. The new features make the range more robust, and enable faster, easier maintenance for customers in the food & beverage and pharmaceutical industries, and operations in other sanitary environments requiring high cleanliness.

The new range complies with the strict health and safety regulations in these industries. The range allows for proper, fast and easy cleaning, including with high pressure and temperature water. The hygienic design wall mounted range, HDW, comprises enclosures with a high protection degree and smooth surfaces without any gaps. The enclosures have self-drainable smooth-finished surfaces, a sloped roof leaning 30° with a 30 mm overhang, special HD locks, and concealed door hinges. The hinges now feature a more robust design and positioners that save time when swapping which side the door opens.

The enclosure body and door are made of AISI 304L stainless steel, with hinges now featuring zinc-plated steel. Proper sealing is secured by an all-round removable blue silicone gasket, which is resistant to aggressive cleaning products. The newly designed gasket features molded corners to make removing and replacing it faster and easier for cleaning and replacement operations.

The new features include:

Newly designed gasket corners to improve its fit on the door and save time when removing or mounting it for routine maintenance or cleaning procedures.

 

More robust hinge design and material with new positioners to save time and make it easier to swap which side the door opens.

 

Chamfered front body vertical edges to enable smoother door opening and closing.

   

In addition, a set of HD-specific accessories is now available, including cable glands, wall mounting brackets and levelling feet. The HDW range is certified for ingress protection IP 66/69/69K which makes it possible to use high pressure and temperature water for cleaning.

IP 69  ratings indicate the level of protection of an enclosure against ingress of liquids (IP X9) and dust (IP 6X). During the testing procedures, enclosures are subjected to the high temperatures (80 °C) and high-pressure sprays (approx. 1200 psi) associated with – but more rigorous than – routine sanitary washdown cleaning procedures. IP 69 (IEC) for electrical equipment and IP 69K (DIN) represent the highest level of protection. Products with these ratings are ideally suited for facilities where hygiene and cleanliness are critical.

By complying with high cleanliness requirements and minimizing hygiene risks thanks to self-draining, smooth-finished surfaces and a gap-free design, the HDW enclosure range helps reduce maintenance-related costs and delays. Component failure and unnecessary downtime are avoided as water and dust are prevented from entering the enclosure, including when cleaning with high pressure and temperature water. In summary, the hygienic design wall mounted enclosure range, HDW, brings several benefits in environments where cleanliness is required:

  • Thorough cleaning is fast and easy
  • High pressure and temperature water can be used
  • Hosted equipment and components are well protected from liquids  and dust
